Abstract
A node device that is used in a network system has a packet processing circuit, a buffer for temporarily storing a packet and a selector for selecting a channel to which the buffer is to be connected. The selector can select either a first channel connected to another node device or a second channel connected to the packet processing circuit. The buffer can store a number of packets, and of these packets the one that is addressed to the packet processing circuit is read out when the buffer is connected to the second channel.
